[0023] The terms "first", "second", and the like in the description and claims of the present application and the above drawings are used to distinguish different objects, and are not used to describe a particular order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but can optionally include other steps or units not listed, or can optionally include other steps or units inherent to the process, method, product or device.

[0024] In the present application, "embodiment" means that the specific features, structures or characteristics described in conjunction with the embodiment can be included in at least one embodiment of the present application. The phrase appears at various places in the specification does not necessarily refer to the same embodiment, nor is it independent or alternative to other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present application can be combined with other embodiments.

[0025] The vehicle-mounted device involved in the embodiments of the present application can be an electronic device installed on a vehicle. The vehicle-mounted device can implement functions of audio playing, video playing, and content display. The vehicle-mounted device can include M vehicle-mounted display screens. For example, the vehicle-mounted device can include any one of a vehicle-mounted multimedia device, a vehicle-mounted display device, and the like.

[0026] Please refer to Figure 1 , Figure 1 is a flowchart of a content display method provided by the embodiments of the present application. As shown in Figure 1 , the content display method can include the following steps.

[0027] 101. The vehicle-mounted device acquires to-be-displayed content.

[0028] In the embodiments of the present application, the vehicle-mounted device can acquire to-be-displayed content from a mobile terminal. The to-be-displayed content can include to-be-displayed pictures, to-be-displayed documents, to-be-displayed application interfaces, or to-be-displayed videos.

[0029] Optionally, the to-be-displayed content includes any one of to-be-displayed pictures, to-be-displayed documents, and to-be-displayed applications.

[0030] 102. In a case where a resolution of the to-be-displayed content is greater than a resolution of a vehicle-mounted display screen with the highest resolution among M vehicle-mounted display screens, the vehicle-mounted device splits the to-be-displayed content into N sub-content blocks, M is a positive integer greater than or equal to 2, and N is a positive integer less than or equal to M.

[0031] In the embodiments of the present application, if the resolution of the to-be-displayed content is greater than the resolution of the vehicle-mounted display screen with the highest resolution among the M vehicle-mounted display screens, any one of the M vehicle-mounted display screens cannot completely display the to-be-displayed content without reducing the to-be-displayed content. At this time, the vehicle-mounted device can split the to-be-displayed content into N sub-content blocks, and can display the N sub-content blocks on N vehicle-mounted display screens. The N vehicle-mounted display screens belong to the M vehicle-mounted display screens.

[0032] The M vehicle-mounted display screens can include one or more combinations of a main display screen, at least one auxiliary display screen, at least one instrument screen, and at least one hand-held display screen. The hand-held display screen can be located at a hand-held box. The main display screen can be a center console display screen.

[0033] The vehicle-mounted display screen described above can be any one of a liquid crystal display screen, a light emitting diode (LED) display screen, and an organic light emitting diode (OLED) display screen. The vehicle-mounted display screen described above can be a display screen with a touch function.

[0034] If the content to be displayed comprises an image, the resolution of the content to be displayed can be an image resolution. If the content to be displayed comprises a document, the resolution of the content to be displayed can be a document resolution.

[0035] The resolution of each of the M vehicle display screens is not necessarily the same. For example, the resolution of the main display screen is relatively high, and the resolution of the handheld display screen is relatively low.

[0036] The resolution of a vehicle display screen refers to the number of pixels in the vertical and horizontal directions of the vehicle display screen, in units of px. The resolution of a vehicle display screen is fixed and does not change after the vehicle display screen is manufactured. The resolution of a vehicle display screen can also be referred to as the display resolution of the vehicle display screen.

[0037] Image resolution refers to the resolution at which a digital image is saved and displayed in a computer, and it is directly related to the pixels of the image. For example, a picture with a resolution of 640x480 pixels has a resolution of 307200 pixels, or 300,000 pixels as commonly referred to. A picture with a resolution of 1600x1200 has 2,000,000 pixels. Image resolution refers to the number of points in the length and width of a picture. For the same size image, the higher the image resolution, the more pixels the image is composed of, and the smaller the pixel points, the clearer and more realistic the image

[0038] The image resolution and the display resolution are two different concepts. The display resolution is used to determine the size of the area in which an image is displayed, while the image resolution is used to determine the number of pixels that make up an image. For example, on a display screen with a display resolution of 1024x768, an image with an image resolution of 320x240 occupies about 1 / 12 of the display screen, and an image with an image resolution of 2400x3000 cannot be fully displayed on this display screen.

[0039] If the resolution of the content to be displayed is greater than the resolution of the vehicle display screen, the content to be displayed cannot be fully displayed on the vehicle display screen without being scaled down. If the resolution of the content to be displayed is less than the resolution of the vehicle display screen, the content to be displayed occupies only a portion of the vehicle display screen without being scaled up.

[0040] 103. The vehicle display screen displays the first sub-content block on the corresponding first vehicle display screen, the resolution of the first sub-content block being less than or equal to the resolution of the first vehicle display screen, the first sub-content block being any one of the N sub-content blocks, the first vehicle display screen being one of the N vehicle display screens corresponding to the first sub-content block, the N sub-content blocks corresponding one-to-one to the N vehicle display screens, the N vehicle display screens being included in the M vehicle display screens.

[0041] In the embodiments of the present application, the N sub-content blocks can be displayed in the N vehicle display screens, and the resolution of the sub-content block displayed in each vehicle display screen is less than or equal to the resolution of the vehicle display screen.

[0042] For example, if the resolution of the picture to be displayed is 1920x2160, and the resolution of each vehicle display screen is 1920x720, the picture to be displayed can be divided into three image blocks of the same size, and the three image blocks of the same size are displayed on the three vehicle display screens. Please refer to Figure 2 , Figure 2 is a schematic diagram provided by the embodiments of the present application for displaying a picture to be displayed on three vehicle display screens. As shown in Figure 2 , the picture to be displayed is divided into three image blocks of the same size, and is displayed on three vehicle display screens (such as vehicle display screen 1, vehicle display screen 2 and vehicle display screen 3 shown in Figure 2 ).

[0043] If the content to be displayed includes an application to be displayed, the content to be displayed can include control content and display content, wherein the control content can be a control interface of the application to be displayed, and the display content can be a display interface of the application to be displayed. For example, the application to be displayed can be an audio playing application, and the volume adjustment function, song switching function and play mode selection function of the audio playing application can be displayed on the control interface, and the lyrics, background, lyricist, composer and song introduction of the song can be displayed on the display interface. The control interface can be displayed on at least one vehicle display screen. The display interface can be displayed on at least one vehicle display screen.

[0044] In the embodiments of the present application, after the content to be displayed is divided into N sub-content blocks, the first sub-content block is displayed on the corresponding first vehicle display screen, and since the resolution of the first sub-content block is less than or equal to the resolution of the first vehicle display screen, the resolution of the sub-content block displayed on each vehicle display screen in the N vehicle display screens is less than the resolution of the corresponding vehicle display screen, and the content to be displayed can be completely displayed through the N vehicle display screens, thereby improving the content display effect.

[0045] Optionally, in step 103, the vehicle-mounted device displays the first sub-content block on the corresponding first vehicle display screen, which can specifically include the following steps:

[0046] (11) The vehicle-mounted device renders the first sub-content block by using a bottom layer rendering mode to obtain a rendered first sub-content block;

[0047] (12) The vehicle-mounted device displays the rendered first sub-content block on the first vehicle display screen.

[0048] In the embodiment of the present application, the vehicle-mounted device can render each sub-content block in a system bottom layer rendering manner, and display the rendered sub-content block on the corresponding vehicle-mounted display screen. The system bottom layer rendering manner can improve the display effect of the sub-content block on the vehicle-mounted display screen. System bottom layer rendering refers to rendering by using the bottom layer capability of the system.

[0049] Please refer to Figure 3 , Figure 3 is a flowchart of another content display method provided by the embodiment of the present application. As Figure 3 shown, the content display method can include the following steps.

[0050] 301. The vehicle-mounted device acquires the content to be displayed.

[0051] 302. In the case where the resolution of the content to be displayed is greater than the resolution of the vehicle-mounted display screen with the highest resolution among the M vehicle-mounted display screens, the vehicle-mounted device determines that the content to be displayed is at least divided into X blocks according to the resolution of the content to be displayed and the resolution of each vehicle-mounted display screen among the M vehicle-mounted display screens, where X is a positive integer greater than or equal to 2.

[0052] In the embodiment of the present application, the resolution of each vehicle-mounted display screen among the M vehicle-mounted display screens can be the same or different. If the resolution of the content to be displayed is A, and the resolution of each vehicle-mounted display screen is B, then X = [A / B], where [A / B] represents the upward rounding result of A / B. For example, if A = 2400x1000 and B = 1024x768, then X = [(2400x1000) / (1024x768)] = [3.05] = 4. If A = 2400x2000 and B = 1200x1000, then X = [(2400x2000) / (1200x1000)] = [4] = 4.

[0053] If the resolution of the content to be displayed is A, and the resolution of the M vehicle-mounted display screens includes two types of resolutions, one type is B and the number is F, and the other type is C and the number is G, where B is greater than C, and F+G=M. If A is less than or equal to BxF, then X = [A / B], where [A / B] represents the upward rounding result of A / B. If A is greater than BxF, then X = F+[(A-BxF) / C]. The embodiment of the present application provides a scheme of preferentially displaying large screens (screens with relatively large resolutions), and can also preferentially display small screens (screens with relatively small resolutions), or select according to the position of the screen, or select according to the priority of the screen, which will not be described herein.

[0054] 303、The vehicle-mounted device determines Y vehicle-mounted display screens that meet display requirements from the M vehicle-mounted display screens according to the type of the content to be displayed and fixed position information of the M vehicle-mounted display screens, Y being a positive integer greater than or equal to 2.

[0055] In the embodiments of the present application, whether the content to be displayed is displayed on multiple vehicle-mounted display screens close in position can be determined according to the type of the content to be displayed. The type of the content to be displayed can include pictures, documents, applications, reversing image, navigation interface, etc.

[0056] For example, if the content to be displayed is a picture or a document, in order to improve the split-screen display effect of the picture and the document, the content to be displayed can be displayed on multiple vehicle-mounted display screens close in position. If the content to be displayed is an application, the control content of the application can be displayed on at least one vehicle-mounted display screen close to the driver or the passenger that can be touched, and the display content of the application can be displayed on at least one vehicle-mounted display screen with the largest resolution.

[0057] The fixed position information of the M vehicle-mounted display screens can be the positions of the M vehicle-mounted display screens fixed in the vehicle. The vehicle-mounted display screens can be rotatable display screens and can be fixed in the front row or the rear row of the vehicle or the hand box position.

[0058] The embodiments of the present application can determine Y vehicle-mounted display screens that meet display requirements from the M vehicle-mounted display screens according to the type of the content to be displayed and the fixed position information of the M vehicle-mounted display screens. The Y vehicle-mounted display screens can meet the display requirements from the M vehicle-mounted display screens. Different types of display content have different display requirements, and there are certain requirements for the positions of the vehicle-mounted display screens. Even if there are currently M vehicle-mounted display screens, the M vehicle-mounted display screens do not necessarily meet the display requirements of the content to be displayed. The embodiments of the present application can select Y vehicle-mounted display screens that meet the display requirements from the M vehicle-mounted display screens, thereby improving the display effect of the vehicle-mounted display screens displaying the content to be displayed respectively.

[0059] Optionally, step 303 can include the following steps:

[0060] (21) The vehicle-mounted device determines the priority of the content to be displayed according to the type of the content to be displayed;

[0061] (22) If there are Z vehicle-mounted display screens in the M vehicle-mounted display screens whose current display content has a priority less than the priority of the content to be displayed, the vehicle-mounted device determines that the Z vehicle-mounted display screens meet the priority display requirements of the content to be displayed, Z being a positive integer greater than or equal to 2;

[0062] (23) The vehicle-mounted device determines P vehicle-mounted display screens that meet position display requirements from the M vehicle-mounted display screens according to the type of the content to be displayed and the fixed position information of the M vehicle-mounted display screens.

[0063] The vehicle-mounted device determines the intersection of the Z vehicle-mounted display screens and the P vehicle-mounted display screens as the Y vehicle-mounted display screens, and the Y vehicle-mounted display screens meet the priority display requirement and the position display requirement.

[0064] In the embodiments of the present application, some of the M vehicle-mounted display screens can be currently displaying content (these display screens can be displaying content, or can be in a sleep state, such as displaying a screen saver, or can be in a power-saving screen-off state), and if the priority of the current display content of Z vehicle-mounted display screens is lower than the priority of the to-be-displayed content, the Z vehicle-mounted display screens meet the priority display requirement of the to-be-displayed content. The Z vehicle-mounted display screens are display screens in a powered-on state. The Z vehicle-mounted display screens refer to all vehicle-mounted display screens in the M vehicle-mounted display screens that can currently be used to display the to-be-displayed content.

[0065] The vehicle-mounted device determines P vehicle-mounted display screens that meet the position display requirement from the M vehicle-mounted display screens according to the type of the to-be-displayed content and the fixed position information of the M vehicle-mounted display screens.

[0066] The P vehicle-mounted display screens refer to vehicle-mounted display screens in the M vehicle-mounted display screens that meet the multi-screen display effect of the to-be-displayed content. Some content has a requirement for the display position. For example, for picture and document content, in order to facilitate the viewing effect of the driver or passenger, the P vehicle-mounted display screens are all located in the front row or all located in the rear row.

[0067] Generally, the priority of the reversing image > the priority of the navigation interface > the priority of the application > the priority of the picture or document. For example, if a display screen is currently displaying navigation or a reversing image, the priority is relatively high. At this time, if picture or document to-be-displayed content needs to be displayed, since the priority of the to-be-displayed content is relatively low, the display screen will not be occupied to display the to-be-displayed content.

[0068] For example, there are five display screens in the vehicle, three screens in the front row are relatively close, and two screens in the rear row. For the display of a complete picture, if part of the picture is displayed in the front row and part of the picture is displayed in the rear row, the display effect of the entire picture will be affected, and therefore it is necessary to find display screens that meet the position requirement.

[0069] The embodiment of the application can determine Z vehicle-mounted display screens meeting the priority display requirement of the to-be-displayed content from M vehicle-mounted display screens according to the priority of the to-be-displayed content, select P vehicle-mounted display screens meeting the position display requirement of the to-be-displayed content from the M vehicle-mounted display screens, so that the selected P vehicle-mounted display screens can meet the priority display requirement and the position display requirement, do not occupy the display screen with a higher priority of currently displayed content, do not affect the display of the content with a higher priority currently displayed, and can meet the position display requirement of the to-be-displayed content, thereby improving the display effect of the vehicle-mounted display screens in displaying the to-be-displayed content.

[0070] 304. If X is less than or equal to Y, the vehicle-mounted device selects N vehicle-mounted display screens from the Y vehicle-mounted display screens, X is less than or equal to N, and N is less than or equal to Y.

[0071] In the embodiment of the application, X is less than or equal to Y, indicating that the Y vehicle-mounted display screens can meet the requirement of complete display of the to-be-displayed content, and then N vehicle-mounted display screens are selected from the Y vehicle-mounted display screens, and the N vehicle-mounted display screens are used to display the to-be-displayed content.

[0072] 305. The vehicle-mounted device divides the to-be-displayed content into N sub-content blocks, M is a positive integer greater than or equal to 2, and N is a positive integer less than or equal to M.

[0073] 306. The vehicle-mounted device displays a first sub-content block on a corresponding first vehicle-mounted display screen, the resolution of the first sub-content block is less than or equal to the resolution of the first vehicle-mounted display screen, the first sub-content block is any one of the N sub-content blocks, the first vehicle-mounted display screen is one of the N vehicle-mounted display screens corresponding to the first sub-content block, the N sub-content blocks correspond to the N vehicle-mounted display screens one by one, and the N vehicle-mounted display screens are included in the M vehicle-mounted display screens.

[0074] The specific implementation of step 301 in the embodiment of the application can refer to the specific implementation of step 101, and steps 305 and 306 can refer to the specific implementation of steps 102 to 103, which will not be described here.

[0075] Please refer to Figure 4 , Figure 4 is a flowchart of another content display method provided by the embodiment of the application. As shown in Figure 4 , the content display method can include the following steps.

[0076] 401. The vehicle-mounted device obtains to-be-displayed content.

[0077] 402、in case that the resolution of the content to be displayed is greater than the resolution of the highest-resolution car display screen among the M car display screens, the car equipment determines that the content to be displayed is at least divided into X blocks according to the resolution of the content to be displayed and the resolution of each car display screen among the M car display screens, X being a positive integer greater than or equal to 2.

[0078] 403、the car equipment determines Y car display screens meeting the display requirements among the M car display screens according to the type of the content to be displayed and the fixed position information of the M car display screens, Y being a positive integer greater than or equal to 2.

[0079] 404、in case that X is greater than Y, the car equipment determines a region containing key content in the content to be displayed, and determines that the region containing key content is at least divided into Z blocks according to the resolution of the region containing key content and the resolution of each car display screen among the M car display screens, Z being a positive integer greater than or equal to 2.

[0080] The key content can include key information in a picture. In case that the content to be displayed is a picture, the key content can include a person, a face, a building, a scenery, etc. In case that the content to be displayed is a document, the key content can include text. In case that the content to be displayed is an application, the key content can include an application main interface, an application control interface, etc.

[0081] In the embodiments of the present application, in case that X is greater than Y, indicating that the Y car display screens cannot meet the requirement of complete display of the content to be displayed, a region containing key content is selected from the content to be displayed, and the region containing key content is divided into N sub-content blocks and displayed on the N car display screens respectively, so as to ensure that the N car display screens can completely display the region containing key content in the content to be displayed, and ensure that the key content can be completely displayed on multiple screens.

[0082] The car equipment determines that the region containing key content is at least divided into Z blocks according to the resolution of the region containing key content and the resolution of each car display screen among the M car display screens, which is similar to step 402, and the specific implementation can be referred to the specific implementation of step 402.

[0083] Optionally, in step 404, the car equipment determines the region containing key content in the content to be displayed, comprising:

[0084] (31) the car equipment detects key point information in the content to be displayed;

[0085] (32) the car equipment determines the region containing key content in the content to be displayed according to the key point information; wherein the same key content is avoided to be divided when the content to be displayed is divided.

[0086] The key point information can include face information and text information. The vehicle-mounted device can detect face information in the to-be-displayed content by using a face recognition algorithm, and can detect text information in the to-be-displayed content by using a text recognition algorithm. The vehicle-mounted device determines a region containing key content in the to-be-displayed content according to the key point information, so that the resolution of the region containing key content in the to-be-displayed content is less than the resolution of the to-be-displayed content. Therefore, the N vehicle-mounted display screens can display the region containing key content in the to-be-displayed content completely, and the key content can be displayed completely on multiple screens.

[0087] The same key content can be the same face or the same text. When the to-be-displayed content is segmented, the same key content is avoided from being segmented and displayed on different vehicle-mounted display screens, thereby improving the user viewing experience. As shown in FIG. 4B, the same face is not displayed on different vehicle-mounted display screens. Figure 2

[0088] 405, if Z is less than or equal to Y, the N vehicle-mounted display screens are selected from the Y vehicle-mounted display screens, and Z is less than or equal to N.

[0089] 406, the vehicle-mounted device segments the region containing key content into N sub-content blocks, M is a positive integer greater than or equal to 2, and N is a positive integer less than or equal to M.

[0090] 407, the vehicle-mounted device displays a first sub-content block on a corresponding first vehicle-mounted display screen, the resolution of the first sub-content block is less than or equal to the resolution of the first vehicle-mounted display screen, the first sub-content block is any one of the N sub-content blocks, the first vehicle-mounted display screen is one of the N vehicle-mounted display screens corresponding to the first sub-content block, the N sub-content blocks correspond to the N vehicle-mounted display screens one by one, and the N vehicle-mounted display screens are included in the M vehicle-mounted display screens.

[0091] The specific implementation of step 401 in the embodiment of the present application can refer to the specific implementation of step 101, and steps 406 and 407 can refer to the specific implementation of steps 102 to 103. Details are not repeated here.
